To those Mac users waiting diligently for a great first-person shooter that isn't Marathon, you'll have to wait a little longer. Call of Duty 4's Mac port has been pushed from it's original release date to Q3 2008. Thankfully, this isn't much of a move for the release date, and Mac users will soon be able to kill terrorists as morally questionable SAS thugs (you know, just like real life). There's no word on whether the bonus maps (pictured above) will make it into the port, be available for download, or neither.
